I have what looks like milk coming from my boob. I don't think i'm pregnant, but it was really freaking me out, please someone let me know. It's just a little coming out, I don't think i've noticed it before

You should see a doctor and have this checked. It matters if the milk is coming from just one or both boobs and if it is coming with or without stimulation. If it is coming with stimulation, it could be due to overstimulating or other benign causes. It is more serious if the milk is coming without any stimulation.

There could be a number of reasons: an infection inside the breast (the discharge would appear in just one breast), high prolactin levels (that have other causes including benign brain tumor), breast cysts, etc
